Compact, portable resistance heating device
A compact, portable resistance heating device that takes a source of alternating current electricity and through a series of connections and circuitry splits the alternating current electricity into a plurality of circuits. The compact, portable resistance heating device is capable of heating a plurality of cartridge heaters at one time, individually or a combination thereof. The compact, portable resistance heating device is controlled by at least one controller that controls three (3) power output receptacles. The controller is capable of producing 0-100% output power to each respective cartridge heater. Each cartridge heater may be individually controlled by an on/off switch, and an indicator light may be provided and illuminate when each cartridge heater is energized. The cartridge heaters of the compact, portable resistance heating device do not require close tolerances with an axial bore of a stud or threaded bolt and are further capable of being bent to suit the particular operation.
1. A compact, portable resistance heating device, comprising:
a compact, portable housing configured to be connected to a source of three-phase alternating current electricity; said device configured to split said three-phase alternating current electricity into separate legs of single-phase alternating current electricity; and
a step-down transformer configured to power a controller; said transformer configured to provide no voltage recognition; said controller configured to control a plurality of receptacles; said receptacles connected to said housing and configured to receive said single-phase alternating current electricity; said controller configured to selectively output said single-phase alternating current electricity to each of said receptacles; and said controller configured to balance said electric output of each of said receptacles based on a number of powered cartridge heaters.
2. The compact, portable resistance heating device of claim 1 wherein said three-phase alternating current electricity is 480 volt three-phase alternating current electricity.
3. The compact, portable resistance heating device of claim 1 wherein said output of said single-phase alternating current electricity is 480 volt single-phase alternating current electricity.
4. The compact, portable resistance heating device of claim 1 wherein each of said cartridge heaters are configured to be powered individually or in a combination thereof.
5. The compact, portable resistance heating device of claim 1 wherein said housing further includes an indicator lamp and an on/off switch associated with each of said receptacles.
6. The compact, portable resistance heating device of claim 5 wherein said on/off switch associated with each of said receptacles enables a user to selectively control an electric output of each of said receptacles.
7. The compact, portable resistance heating device of claim 1 wherein said controller is capable of varying said output of said single-phase alternating current electricity between 0% and 100%.
8. The compact, portable resistance heating device of claim 7 wherein said controller comprises a plurality of controllers electrically connected to said step-down transformer.
9. The compact, portable resistance heating device of claim 7 further comprising a plurality of circuits for respectively providing said single-phase alternating current electricity to a plurality of receptacles.
10. The compact, portable resistance heating device of claim 1 wherein said housing further includes an external junction box for connection of said source of three-phase alternating current electricity.
11. The compact, portable resistance heating device of claim 1 further comprising a circuit breaker arranged to deliver said source of three-phase alternating current electricity through said controller and said transformer to said plurality of receptacles.
12. The compact, portable resistance heating device of claim 1 further comprising a plurality of cartridge heaters configured to respectively output said single-phase alternating current electricity from said receptacles; wherein each of said cartridge heaters includes a cartridge heater cable at one end terminating with a plug configured to be received in one of said receptacles and having a heating element at an opposite end.
13. The compact, portable resistance heating device of claim 12 wherein said heating element of each of said cartridge heaters comprising an internal heating rod constructed of a thermal conducting material surrounded by a dielectric fluid insulator sheathed within an outer casing.
14. The compact, portable resistance heating device of claim 13 wherein each of said cartridge heaters provides wattage of up to approximately 2000 watts and amperage between approximately 4 and approximately 30 amps.
